Little John's: Galvanized Square Steel

The mod adds a set of building blocks that cover existing blocks in a thin layer. Plank, log, leaf, moss grass, bamboo, crimson and warped veneers can be placed over other blocks, and cherry blocks produce leaf particles. Galvanized square steel grates, beams and screws give industrial-looking frameworks, and cherry planks, leaves and fences combine with them. Covered blocks can be waterlogged, and none of the new pieces need support blocks.

Fabric Language Kotlin is required, so it must be installed alongside the mod. Polymorph and Roughly Enough Items (REI) are optional and add integration when present. Little John's: Galvanized Square Steel runs on client and server, so both the server and every player need it. The source code and issue tracker are public, and the code is released under the MIT License. Files exist for 1.20.6, 1.21.3 and 1.21.5, and the latest Fabric build is 0.1.9-1.21.5 for 1.21.5, published on 2025-05-25.
